Fabrication of an epoxy-insulated Marshall Coil

PDF Version Also Available for Download.

Description

A Marshall Coil was fabricated by the LASL CMB-6 Materials Technology Group for use in an electrical testing program to evaluate the Marshall Coil concept. The coil is basically a hat-shaped epoxy insulator which was electroplated with copper on all surfaces, and a complex conductor pattern was machined out of the copper. The brim of the coil is approximately 84 cm diameter and the crown is 24 cm high. Other techniques for fabricating Marshall Coils were studied, the one selected being that which was felt to offer the best chance of success on a one-time basis. Alternate proposals involved (a) ... continued below

Alternate proposals involved (a) the potting of a freestanding copper insulator array in epoxy resin, and (b) inlaying stamped copper conductor sections in the slots of a machined epoxy insulator.
